Manufactured to the highest quality standards, GOLIA triple function air valves are the ideal choice for corrosive media and marine environments. Made in various materials such as AISI 316 stainless steel, DUPLEX and SUPER DUPLEX. They feature the anti water hammer mechanism through RFP technology (a device that prevents rapid filling) and AS (anti-shock mechanism), both designed to prevent the unwanted water hammer caused by rapid closing.
